Light Source Gives Quantum Info Processing a Sense of Direction
HARBIN, China, Sept. 21, 2022 — Researchers from Harbin Institute of Technology and Australian National University used bulk states in the continuum (BICs) to develop metasurfaces — doped with light-emitting molecules — that operate as compact sources of chiral light. The researchers’ efficient, controllable emission mechanism for circularly polarized light also yielded chiral lasing. According to the researchers, the method will be useful for the development of integrated optical devices. Up to now,
